Re: [Fab-user] entering password multiple times on invoke

[Christian Vest Hansen]

Fabric caches the passwords on a per-host basis. However, this cache
is defeated by `invoke()` for some reason.

Note that `invoke()` only makes sense if you really do not want to
execute the specified command if it has already been executed with the
given arguments in the Fabric-session.

If it really bothers you, then you can work around the issue by
letting the invoked command, in this case "bar", set a flag on the
config object and return immediately if it is already set.

I would personally like to not have to tinker with this part of the
code for the time being.
